READ AND SAVE THESE INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer at the address or
telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel
and lock the service disconnecting means to prevent power from
being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to
prevent backdrafting. Follow the heating equipment manufacturer's
guidelines and safety standards such as those published by the
National Fire Protection Association (NFPA), and the American
Society for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
6. The wiring must be permanent. DO NOT USE AN EXTENSION
CORD! Use 14 GA. MINIMUM copper wire. Although the Powered
Attic Ventilator may be wired directly to power, we advise that
some type of shut off switch be installed in the line. Please see the
section on electrical wiring for suggested wiring diagrams and
instructions.
7. This unit must be grounded.
CAUTION
1. For general ventilating use only. Do not use to exhaust hazardous
or explosive materials or vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power unit.
TOOLS & MATERIALS REQUIRED
… Screwdrivers (Slotted & Phillips)
… Hammer
… Ruler
… Pencil
… Electrical supplies (to comply with codes)
… Nails
PREPARE THE VENTILATOR
1. Unpack the ventilator and find:
1 - power unit with wiring box
4 - angle brackets
8 - sheet metal screws
CAUTION
3. This unit has an unguarded impeller. Do not use in locations readily
accessible to people or animals.
4. Fan is equipped with a thermostat which may start fan
automatically. To reduce risk of injury or electric shock while
servicing and cleaning unit, switch power off at service panel and
lock service panel to prevent power from being switched on
accidentally. When the service disconnecting means cannot be
locked, securely fasten a prominent warning device, such as a
tag, to the service panel.
5. Home Ventilating Institute (HVI) recommends one square foot of
open air inlet per 300 cfm of fan capacity. The best location for
these air intake vents are under the eaves with direct access to
the attic. Vents for attic side wall installations should be placed at
the end of the house opposite the installed ventilator. Failure to
provide these intakes could cause natural-draft gas appliances to
backdraft.
6. Your attic installation will create a screened opening into your attic
space. During a heavy rainstorm there could be a light spray of
rain into this attic space. This is a normal condition with all attic
ventilators and will not cause any damage to the structure.We
recommend that you do not store any valuable articles directly
under the fan opening in the gable. During extreme rain and wind
storms you may want to turn on your attic ventilator to prevent
excess mositure accumulaltion in your attic.
7. Records show, under ideal conditions, exposed galvanized steel
can remain rust free up to 100 years. For best protection, the
exposed portion of the roof sheet should be painted, especially in
areas of unusually high industrial air pollution. Follow paint
manufacturer’s instructions for good adhesion.
8. This ventilator is intended for Gable installation. The Broan Models
350, 355, 356 & 358 Roof Mount Ventilators are available for roof
mount applications.
9. Please read specification label on product for further information
and requirements.
2. Fasten the four (4) angle mounting brackets to the housing
using the eight (8) sheet metal screws provided. Position
the bracket flush with the edge of the housing band. A close
fit between ventilator and louver will minimize air
recirculation.
INSTALL THE VENTILATOR
1. The ventilator is designed to mount behind existing louvers.
Find the type of louver you have in the examples below. If no
louver exists, one must be installed. Louver should be mounted
in the center of the upper portion of the gable as high as possible. For maximum efficiency, the area of the louver should
be greater than the outlet area of the ventilator.
The ventilator can also be mounted off-center in an odd shaped
louver.
There is some loss in fan output because the louver blocks
some of the air flow. Metal louvers have more open area than
wood louvers and usually allow more air flow.
When installing the ventilator behind louvers, you should seal
off any louver area not covered by the ventilator housing band
to prevent air leakage and recirculation. We suggest you
mount the ventilator on a piece of plywood for best sealing.
Allow at least one square foot of air intake area for every 300
CFM of ventilator capacity.
CAUTION! When installing louvers or shutters, do not
remove any existing structural members without providing alternate support members.
On large triangular louvers, mount to the frame or nail boards
to the frame to provide a mounting surface for the ventilator.
For the most effective installation, enclose the louver area
not covered by the fan, with plywood or similar material.
The ventilator can be mounted flush to a rectangular type
louver by fastening through the mounting brackets to the frame
of the louver.
On a wide louver the brackets can first be fastened to the
backside of two boards of the appropriate length and these
boards can then be fastened to the frame.
Louvers that are smaller than the ventilator outlet will restrict
air delivery. When this condition exists, a chamber should be
built to properly direct the air through the louvers. A typical
example of the suggested construction is shown.
With a narrow louver mounted between studs on 16” centers,
two of the brackets can first be mounted to the backside of
boards and the boards and other brackets nailed to the studs.
An automatic shutter, Model 433, may also be installed to
provide the necessary outlet for the fan. Installation instructions are provided with the Model 433 shutter.

2. For standard installation, connect the two leads in the thermostat wiring box to the two power leads. Attach ground wire
from the power cable to the green screw in the box.
4. The thermostat setting determines the temperature at which
the ventilator turns “on”. The ventilator automatically turns off
when the attic temperature is 10OF lower than the thermostat.
If you want the ventilator to operate at a different temperature, insert a screwdriver into the slot and turn the indicator to
the desired temperature.
